21) When replacing bearings, tap front bearing cup and
rear bearing cup in this order out of case by using a brass
bar.
D: INSPECTION
Wash all the disassembled parts clean, and examine them
for wear, damage, or other defects. Repair or replace
defective parts as necessary.
1) Crown gear and drive pinion
(1) If abnormal tooth contact is evident, find out the
cause and adjust to give correct tooth contact at
assembly. Replace the gear if excessively worn or inca-
pable of adjustment.
(2) If crack, score, or seizure is evident, replace as a
set. Slight damage of tooth can be corrected by oil
stone or the like.
2) Side gear and pinion mate gear
(1) Replace if crack, score, or other defects are evident
on tooth surface.
(2) Replace if thrust washer contacting surface is worn
or seized. Slight damage of the surface can be cor-
rected by oil stone or the like.
3) Bearing
Replace if seizure, peeling, wear, rust, dragging during
rotation, abnormal noise or other defect is evident.
4) Thrust washers of side gear and pinion mate gear
Replace if seizure, flaw, abnormal wear or other defect is
evident.
5) Oil seal
Replace if deformed or damaged, and at every disassem-
bling.
6) Differential carrier
Replace if the bearing bores are worn or damaged.
7) Differential case
Replace if its sliding surfaces are worn or cracked.
8) Companion flange
Replace if the oil seal lip contacting surfaces have flaws.

TOOTH CONTACT PATTERN
Condition Contact pattern Adjustment
Correct tooth contact
Tooth contact pattern slightly shifted
towards toe under no load rotation.
(When loaded, contact pattern moves
toward heel.)
B3M0317A
Face contact
Backlash is too large.This may cause noise and chipping at
tooth ends.
B3M0319
Increase thickness of drive pinion height
adjusting shim in order to bring drive
pinion closer to crown gear center.
B3M0323
Flank contact
Backlash is too small.This may cause noise and stepped wear
on surfaces.
B3M0320
Reduce thickness of drive pinion height
adjusting shim in order to move drive
pinion away from crown gear.
B3M0324
Toe contact
Contact area is small.This may cause chipping at toe ends.
B3M0321
Adjust as for flank contact.
B3M0324
Heel contact
Contact area is small.This may cause chipping at heel ends.
